Power
generators are mainly applied for telecoms stations in telecoms industry.
Usually, generator sets 800KW are needed for provincial station, and generator
sets 300KW to 400KW are needed for municipal station, as standby power. For town
or county station, 120KW and below are needed, usually as prime power.
Requirements and Challenges
1.
Automatic functions
Auto start and auto loading
After receiving the start directive, the machine will start
up automatically, with 99% success ratio. A start circle containers three start
attempts. The interval between two start attempts is 10 to 15 seconds.
After successful start up, when the oil pressure reaches
set value, the machine will load automatically. The load time is usually 10
seconds.
After three times of startup failure, the machine will give
alarm reporting, and give start directive to the other standby generator set,
if there is any.
Auto stop
When receiving the stop directive, the machine will stop
automatically. There are two types: normal stop and emergency stop. The normal
stop is to stop the power (and then break the air switch or switch ATS to the
main). The emergency stop is to cut the power and fuel supply immediately.
Auto protection
The machines have protection against low oil pressure, over
voltage, over speed, overload, short circuit and lack of phase. For
water-cooled machines, also high water temperature protection is provided and
high cylinder temperature protection for air-cooled machines.
2.
Remote Control
The machine provides remote control system, monitoring the
real time operation parameters and state. When abnormality or serious faults
occur, the machine will give alarms. Standard communication protocols can be
provided.
3.
Paralleling operation
It can be realized through ATS auto switch between the main
and generator or between two generators . Also, two or more same model
generators can be paralleled to ensure bigger capability. The stable state
speed regulation ratio is between 2% and 5%. The stable state voltage
regulation is within 5%.
4.
Altitude height 3000 meters and below. Temperature lower limit -15℃, upper
limit 40℃
Power Solution
Superb power generators, with digital control module and
ATS, assures immediate power supply at the same time the main is gone.
Advantages
• Whole set product and turn-key solution help customer use
the machine easily without much technical knowledge. The machine is easy to use
and maintain.
• The control system has AMF function, which can auto start
or stop the machine. In emergency the machine will give an alarm and
stop.
• ATS for option. For small KVA machine, the ATS is
integral.
• Low noise. The noise level of the small KVA machine
(30kva below) is below 60dB(A)@7m.
• Stable performance. Average failure interval is not less
than 2000 hours.
• Compact size. Optional devices are provided for special
requirements for stable operation in some freezing cold areas and burning hot
areas.
• For bulk order, custom design and development is
provided.
